ROTI ® ImmunoBlock is an innovative blocking reagent on a polymer base without detergents and proteins Suitable for: Immunocytological assays Immunohistological assays Paraffin- and cryosections in situ hybridisation Cell culture samples Whole mount samples ROTI ® ImmunoBlock 10x conc., ready-to-use The protein-free formulation prevents contamination of your detection systems by foreign proteins. Unspecific interactions of the detection reagents such as antibodies with proteins of the samples are suppressed, while the specific binding sites are retained. The signal to noise ratio is considerably increased and signal detection significantly improved. The practical ready-to-use solution makes tedious preparation unnecessary. Since the assays can be performed completely in ROTI ® ImmunoBlock, highly reproducible results are achieved. Figure: Scilla siberica : Cross section of a conducting bundle from the leaf.
